Electrical w/2003 chevrolet silverado 2500HD

Remote keyless entry, (both doors), power door locks both doors, right door power window and mirror adjust will not work. Right window will not work from either door nor will door lock. Turn signal in right mirror does work as well as the one in the left. Both 25 Amp circuit breakers for doors are OK. This came on suddenly. One day it was working and the next not.

    my truck is a 1500 and i'm having the same problem. my driver side still works but even my driver side will not do anything to my passenger side (i.e. let the window down or lock the door). the passenger side won't do anything either.

SOURCE: 2003 Chevy 2500HD Dash Gauges not working

There are known issues with the gauges on the 03 silverado. Even though the cages appear analog, they are stepper motor controlled by the computer. This is a fancy way of saying digital. Check with the dealer about a recall! Since all gauges appear to have quit at one time I would agree with a previous post that the computer program is flawed. It may need to be reset - again check with the dealer.

Instructions to program a keyless entry remote for a Chevy Silverado. They also work on 2003, 2004 and 2006 Suburbans.
  1. Close all the vehicle doors.
  2. Insert the ignition key into the ignition lock cylinder.
  3. Press and hold the DOOR unlock switch.
  4. While holding the DOOR lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
  5. Release the DOOR unlock switch. The doors will lock and unlock to confirm the program mode.
  6. Press and hold the LOCK button and the UNLOCK button simultaneously on one keyless remote. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
  7. Repeat the previous step to program up to four transmitters.
  8. Turn the ignition switch to the RUN (one more click forward) position in order to exit the keyless entry transmitter mode.
  9. Operate the transmitter functions in order to verify correct system operation

Power windows and door locks don't work on 2006 silverado


it's not the girlfriend, it is the PDM, passanger door module, got mine a rock auto for 120.00, need to get the one specific for your VIN, not on most parts lists, it is a control board for all power windows and locks and the keyless entry. My cadillac was doing exsactly what your truck is doing. once you put the new one in you need to reprogram the remotes, not too hard, hold down lock button on drivers door, ignition on/off twice, let go of the door lock button, press both unlock, lock buttons and hold untill you hear the lock unlock. your program sequence might be slightlyl different check the web.
good luck.
